Abstract

A high efficiency, low pollution engine utilizing a source of ultrasonic energy to produce atomization of the fuel or fuel mixture preparatory to or after the fuel has been delivered to the combustion chambers of the engine; the means for producing the ultrasonic energy including in part the high pressure gases or gaseous mixture produced by the engine itself during operation thereof. The high pressure gases are caused to pass over or through a suitable whistle like structure that produces high frequency or ultrasonic sound wave energy which is selectively communicated to the fuel prior to the same being ignited within the engine'"'"''"'"'s combustion chambers and/or to the engine exhaust.

Claims

1. In an engine having at least one combustion chamber, first means including a source of pressurized gas from said engine for producing ultrasonic energy, and second means for subjecting the fuel mixture to said ultrasonic energy in order to atomize said mixture and thereby promoting efficient, pollution-free combustion said means including passage means formed directly in said engine for communicating said source of pressurized gas with said cylinder.

2. The invention as set forth in claim 1 which includes accumulator means for receiving and storing preselected quantities of said ultrasonic energy.

3. The invention as set forth in claim 1 wherein the engine comprises a plurality of combustion chambers and which includes integrally formed flow passage means located proximate and communicating each of said chambers with means for producing ultrasonic energy.

4. The invention as set forth in claim 3 which includes a separate means for producing ultrasonic energy for each of said combustion chambers.

5. The invention as set forth in claim 3 which includes a common means for producing ultrasonic energy for each of said combustion chambers.

6. The invention as set forth in claim 3 which includes accumulator means for containing preselected quantities of said ultrasonic energy and passage means communicating each of said combustion chambers with said accumulator means.

7. The invention as set forth in claim 1 wherein the engine comprises an intake manifold for introducing air-fuel charges into said combustion chamber, and wherein said means for producing ultrasonic energy is unitized with said intake manifold.

8. The invention as set forth in claim 7 wherein said passage means includes first flow path means communicating said combustion chamber with said means for producing said ultrasonic energy and second flow path means communicating said means for producing ultrasonic energy with said intake manifold.

9. The invention as set forth in claim 1 wherein said second means includes an ultrasonic energy producing structure, first flow path means communicating said combustion chamber with said structure in order to communicate pressurized gas from said chamber to said structure, and secoNd flow path means communicating said structure with said combustion chamber in order to transmit ultrasonic energy from said structure to said chamber.
